at the very least, it would be a little more helpful if you had a "switch accounts" button on the main menu that saved usernames of other personal accounts to make it easier to sign out and into a different personal account. Free Gmail on the web does it that way.

I know lots of apps use the ellipsis/three dots (...) when the text reaches a character limit, but I think it's a little annoying when you have to go to the properties of the file/folder just to see it's full name. Just make a new type of view (detailed view?) or make it as an option in settings.

It would be nice if the android app would use the same sorting default as the one set in our OneDrive on the web. As of right now, we have to sort every folder manually since the app's default is by icons.

Would also be nice to set a default sorting for the app with just one tap that would sort it all from the root to the last subdirectory.

Sometimes, one needs to upload big but not urgent files so it's just not worth it to use too much cellular data, so then the wifi-only option would be great. And in the same circumstance of not urgent files uploading, pausing the upload temperarily for some urgent need of quick network usage is also convenient.

Currently OneDrive for Android has an artifical limit on what files you can open. It would be very useful if that block was removed so that any file can be opened as long as there is an app installed that supports that file extension.

Add the possibility to cancel the upload of a photo or video on onderive. Also you can pause this without having to go offline would be nice to!
And more, the ability to choose which folders of gallery to synchronize.

Within the Android app, OneDrive suggests you backup photos from multiple apps/folders/sources on your phone. This is a good feature to keep everything synced with the cloud, however it is very disorganized to throw all of these files in the base Camera Roll folder. Each source (every app/folder) should have it's own folder within Camera Roll. They all have different naming conventions, so it's difficult to dissect which photo came from which app.

What was this not a standard feature when first developed?
If someone is using a Windows 10 computer, they sync folders.
Those same folders should be able to be synced on the Android device.
Please, for the love of God, add folder sync. This should have never been released without it.
Thank you.

It is a bit silly that OneDrive for Android uses on average 64MB of RAM when just sitting idle in the background.

OneDrive support even refused to answer why it needs to force itself to stay running in the background all the time so if it actually isn't needed the high memory usage is even worse. Forcing an app to remain running all the time if it isn't needed is called "one of the worst memory management mistakes an app can make" in the Android SDK documentation.
